10 Questions
Which type of experimental design relies on systematic observation and data collection for making conclusions?
Classic Experimental Designs
What aspect is considered the most important in an experiment setup?
Control over extraneous variables
What is the term used for a variable that affects the dependent variable but is not of interest to the researcher?
Extraneous variable
In experimental design, what is the term for a variable that has a systematic effect on behavior but is not controlled by the experiment?
Confounding variable
Which type of design involves comparing groups that have been exposed to different treatments or conditions?
Exposed/Comparison Group Design
What is the term used for various levels of treatment that are identified and studied in an experiment?
Treatment levels
Which type of experimental design allows scientists to recreate a research study?
Replicable Experimental Designs
'Extraneous variables' in an experiment refer to variables that:
Affect the dependent variable but are of no interest to the researcher
'Control' in an experiment is primarily concerned with:
Controlling extraneous variables that may impact the results
In an experiment, what term refers to a factor affecting behavior but not controlled by the researchers?
Extraneous variable
This quiz covers the methods of blocking (stratification) to control for key variables in research, such as randomizing within specific blocks like gender or baseline weight. It also discusses the importance of establishing baseline stability in the dependent variable measure before the study treatment begins.
